ATLANTA — Across the South, winter-weary residents woke up Wednesday to a region encased in ice, snow and freezing rain, with forecasters warning the worst of the potentially “catastrophic” storm is yet to come.

From Texas to the Carolinas and the South’s business hub in Atlanta, roads were slick with ice, tens of thousands were without power, and a wintry mix fell in many areas. The Mid-Atlantic region also was expected to be hit as the storm crawled north and east.

Officials and forecasters in several states used unusually dire language in warnings, and they agreed that the biggest concern is ice, which could knock out power for days in wide swaths. Winds, with gusts up to 30 mph in parts of Georgia, promised to exacerbate problems.

In Atlanta, where a storm took the metro region by surprise and stranded thousands in vehicles just two weeks ago, tens of thousands of customers were reported without power across the state. City roads and interstates were largely desolate, showing few vehicle tracks as most people heeded warnings to stay home.

Stinging drops of rain fell, punctuated by strong wind gusts, and a layer of ice crusted car windshields. Slushy sidewalks made even short walking trips treacherous. One emergency crew had to pull over to wait out the falling snow before slowly making its way back to the Georgia Emergency Management Agency’s special operations center.

In normally busy downtown areas, almost every business was closed, except for a CVS pharmacy.

Amy Cuzzort, 32, was out walking her dog. She teaches in Atlanta, but school was canceled. Cuzzort, who spent six hours in her car during the traffic standstill of January’s storm, said she’d spend this one at home, “doing chores, watching movies — creepy movies, ‘The Shining.’”

In Decatur, Georgia State University student Matt Stanhope, 23, ventured outside to go to a pharmacy but then planned to stay home.

“Everything is just on pause,” he said, gazing at vacant streets.

Cuzzort and Stanhope were doing exactly as officials advised. Georgia Gov. Nathan Deal and Atlanta Mayor Kasim Reed had implored people Tuesday night to get somewhere safe and stay there.

“The message I really want to share is, as of midnight tonight, wherever you are, you need to plan on staying there for a while,” Reed said. “The bottom line is that all of the information that we have right now suggests that we are facing an icing event that is very unusual for the metropolitan region and the state of Georgia.”

In an early Wednesday memo, the National Weather Service called the storm “an event of historical proportions.”

The forecast drew comparisons to an ice storm in the Atlanta area in 2000 that left more than 500,000 homes and businesses without power and an epic storm in 1973 that caused an estimated 200,000 outages for several days. In 2000, damage estimates topped $35 million.

Eli Jacks, a meteorologist with National Weather Service, said forecasters use words such as “catastrophic” sparingly.

“Sometimes we want to tell them, ‘Hey, listen, this warning is different. This is really extremely dangerous, and it doesn’t happen very often,’” Jacks said.

He noted that three-quarters of an inch of ice would be catastrophic anywhere. But the Atlanta area and other parts of the South are particularly vulnerable: Many trees and limbs hang over power lines. When ice builds up on them, limbs snap and fall, knocking out power.

Many Atlanta-area residents, still reeling from the last storm, took more precautions this week — shopping ahead of time and making plans to telecommute. But wedding photographer Matt Altmix, 31, said people were ready for the winter madness to be over.

“After the first snow, we kind of got our snow excitement out of the way. But now it’s more the drudgery of pushing on,” he said.

Around the Deep South, slick roads were causing problems. In North Texas, at least four people died in traffic accidents on icy roads, including a Dallas firefighter who was knocked from an Interstate 20 ramp and fell 50 feet, according to a police report.

Also in Texas, an accident involving about 20 vehicles was reported Tuesday along an icy highway overpass in Round Rock, just north of Austin. Police dispatchers said no serious injuries were reported and the roadway was cleared by Tuesday evening.

In Mississippi, two weather-related traffic deaths were reported.

In northeastern Alabama, two National Guard wreckers were dispatched to help clear jackknifed 18-wheelers on Interstate 65. Alabama Gov. Robert Bentley said one lesson learned from the storm two weeks ago was to get those wreckers organized earlier.

Delta canceled nearly 2,200 flights on Tuesday and Wednesday, most of them in Atlanta.

Atlanta and state officials were widely criticized over their response to the January storm. This time around, some residents noted that the city and its leaders seemed better prepared. “I think some folks would even say they were a little trigger happy to go ahead and cancel schools yesterday,” Altmix said Wednesday. “But it’s justified,” he added.

For Bob Peattie of Bayshore, N.Y., and Lee Harbin of San Antonio, Texas, it was the second time in two weeks that their business meetings in Atlanta were canceled because of bad weather. Both work for a software consulting company were staying put at downtown hotel.

“In two weeks, we’ll do it again,” Harbin said, laughing.

They planned to work as long as the power remained on and they had Internet access.

“We can be sitting anywhere as long as we have connectivity,” Peattie said. “You make the best out of everything.”
